UART Tx Output Level Change
I'd like to interface the UART Tx output of a 4200 PSoC4 running on a 3.3V bus to a device fed with a 5V PS. I don't want to use a level translator.
Is there a way to reconfigure the Tx pin as an Open Drain (and reverse the logic) as the pin is chosen by the fitter, so I have no direct access to its configuration.
May be changing the corresponding registers by software?
